Background
Unprotected left main (ULM) coronary disease is considered by contemporary guidelines as a Class I indication for surgery. However, percutaneous coronary intervention (PCI) is often carried out in the ULM in either emergent or in high risk elective procedures. The aim of this study was to evaluate ULM-PCI as a feasible and safe procedure in the emergent setting, and to analyze outcomes in both scenarios.
Methods
Angiographic and clinical data were collected retrospectively for all patients who underwent emergent or elective PCI on ULM at our center from January 2006 to June 2009. All patients were followed up with a clinical visit or telephone interview. Main outcomes included major adverse cardiac events (MACE) and its individual components: cardiac death, myocardial infarction (MI), and target lesion revascularization. These were analyzed at the longest follow-up available.
